Composite joint configuration
Abstract
A sidewall of a trailer is formed from at least two composite
panels joined together by a novel joining configuration. Each panel
is formed from inner and outer thin metal skins and a plastic core
sandwiched between the skins. A logistics plate is secured by
rivets to the panels for joining them together. The splicing member
is eliminated and instead, the outer skin of at least one panel is
extended to lie behind the logistics plate. An insert may be used
between the skins where the rivets are inserted to substantially
prevent compression of the panels.

Description
BACKGROUND OF THE INVENTION
This invention is generally directed to a novel sidewall for a
trailer body. More particularly, the invention relates to joined
composite panels for trailer bodies, wherein each composite panel
includes a plastic core member sandwiched between thin metal skins
and joined together by novel joints.
Trailer of the general type disclosed herein include a variety of
types of sidewalls. A typical well-known construction is a
panel-type trailer which includes aluminum side posts. Generally,
it is desirable to have a relatively thin trailer sidewall so that
the total inside dimensions of the trailer body can be increased to
carry the optimum amount of cargo. In addition, it is desirable to
have a trailer sidewall which is lightweight.
OBJECTS AND SUMMARY OF THE INVENTION
A general object of the present invention is to provide a novel
joint configuration for joining a pair of composite panels together
in a trailer sidewall, wherein a plurality of such joined panels
may be used to form the trailer sidewall.
An object of the present invention is to provide a novel sidewall
for use in a trailer body, which sidewall is simple in design and
economical to manufacture while at the same time providing maximum
interior space in the trailer body.
Another object of the present invention is to provide a novel
sidewall having a plurality of joined composite panels, wherein
each composite panel includes a plastic core member sandwiched
between thin metal skins.
A further object of the present invention is to provide a novel
sidewall for use in a trailer body, which sidewall is easily
attached to the roof and the floor of the trailer body.
These and other objects and features of the present invention will
become more apparent from a reading of the following
descriptions.
Briefly, and in accordance with the foregoing, the present
invention discloses a sidewall of a trailer which is formed from at
least two composite panels joined together by a novel joining
configuration. Each panel is formed from inner and outer thin metal
skins and a plastic core sandwiched between the skins.
In several embodiments, at least one of the skins has at least one
end coined to as to compress the core between the skins to define a
coined end section. A logistics plate and a splicing member are
used to join the panels together and are secured thereto by rivets.
The logistics plate and/or the splicing member sit against the
coined end sections. The splicing member may have flat top and
bottom portions to facilitate in the attachment of the panels to
the top and bottom rails of the trailer.
In other embodiments, a logistics plate member is secured by rivets
to the panels for joining them together. The splicing member is
eliminated and instead, the outer skin of at least one panel is
extended to lie behind the logistics plate.
In another embodiment, the inner skin may have rolled or formed
grooves to provide a smooth transition from a logistics plate
having rolled edges.
In yet other embodiments, one end of each panel has a thickness
which is less than the other end of the panel. The skins at the
greater thickness end of the panel freely project beyond an end of
the core member. The lesser thickness end is inserted between the
skins of the other panel at the greater thickness end and secured
thereto by rivets. To form the lesser thickness, the end of the
panel may be coined or the panel may taper from one end to the
other end. An insert member, made of hard plastic or metal, may be
used between the skins where the rivet is inserted in any of the
embodiments to substantially prevent compression of the panels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
While the invention may be susceptible to embodiment in different
forms, there is shown in the drawings, and herein will be described
in detail, specific embodiments with the understanding that the
present disclosure is to be considered an exemplification of the
principles of the invention, and is not intended to limit the
invention to that as illustrated and described herein.
Turning now to the drawings, a trailer 20, 20a constructed in
accordance with the present invention is shown in FIGS. 1 and 14.
The trailer 20 of FIG. 1 is shown connected to a tractor 21 by
conventional means, such as a fifth wheel assembly. The trailer 20a
of FIG. 14 can likewise be connected to a tractor. The trailer 20,
20a includes a body 22, 22a formed from a pair of rectangular
sidewalls 24, 24a, a front wall 26, 26a, rear doors 28, 28a, a top
panel or roof 30, 30a and a floor 32, 32a. The floor 32, 32a is
supported by a conventional rear undercarriage assembly 34, 34a and
has a landing gear 36, 36a secured thereunder. The top panel 30,
30a and an upper portion of the sidewalls 24, 24a are secured to a
top rail 38, 38a and the floor 32, 32a and lower portion of the
sidewalls 24, 24a are secured to a bottom rail 40, 40a.
The top rail 38a, as shown in FIG. 14, is an L-shaped member having
a first flat portion 39a and a second flat portion 41a. The first
portion 39a is perpendicular to the second portion 41a. The first
portion 39a of the top rail 38a attaches to the top panel or roof
30a awhile the second portion 41a of the top rail 38a attaches to
the sidewalls 24a. The bottom rail 40a, as shown in FIG. 14, is of
similar construction to the top rail 38a and attaches to the floor
32a and the sidewalls 24a in a similar manner as the top rail 38a
attaches to the roof 30a and the sidewalls 24a. The top and bottom
rails 38a, 40a maybe formed out of aluminum by an extrusion
process.
Each sidewall 24, 24a includes a plurality of vertical upstanding
composite side panels 42, 42a joined together by a novel joint
configuration 44, 44a. Each composite side panel 42, 42a includes a
plastic core member sandwiched between an inner thin metal skin and
an outer thin metal skin and bonded thereto by a suitable known
adhesive or other like means. One advantage of the composite panel
42, 42a used in the present invention is that it can be coined or
stepped down easily by applying pressure to the area to be coined
or stepped down, whereas in the prior art aluminum sidewalls, the
aluminum sidewall could not be easily coined.
The inner skin and the outer skin are preferably approximately
0.026 inches thick. The skins are preferably made of aluminum;
galvanized, full hardened steel, such as AISI Grade E full hard
steel because of its cost effectiveness, or the like. Preferably,
the outer skin is made of ASTM G90 galvanized steel and the inner
skin is made of ASTM G60 galvanized steel. Aluminum may be used,
but it may be too soft for some purposes and strength and punch
resistance are sacrificed, however, aluminum is lightweight.
Typically, each panel 4:2, 42a is four feet in width, but can be
longer or shorter depending on the application. At least two panels
are joined together by the novel joint configuration 44,44a to form
the sidewall 24, 24a of the trailer body 22, 22a.
Each core member is made of some type of compressible non-metal
material, preferably thermoplastic, such as polypropylene or high
density polyethylene These materials are relatively inexpensive as
compared to aluminum found in prior trailer wall constructions. In
addition, because a composite panel 42, 42a is used, the weight of
the trailer construction is reduced over trailers having aluminum
sidewalls.
Attention is now directed to the various embodiments of the novel
joint configuration 44, 44a used in forming the trailer sidewalls
24, 24a as shown in FIGS. 2-13, 15-16. A first embodiment of the
joint configuration 144 is shown in FIG. 2. A second embodiment of
the joint configuration 244 is shown in FIG. 3; a third embodiment
of the joint configuration 344 is shown in FIG. 4; a fourth
embodiment of the joint configuration 444 is shown in FIGS. 5 and
6; a fifth embodiment of the joint configuration 544 is shown in
FIG. 7; a sixth embodiment of the joint configuration 644 is shown
in FIGS. 8 and 9; a seventh embodiment of the joint configuration
744 is shown in FIG. 11; an eighth embodiment of the joint
configuration 844 is shown in FIG. 13; a ninth embodiment of the
joint configuration 944 is shown in FIG. 15; and a tenth embodiment

fourth embodiment being in the four hundreds, the fifth embodiment
being in the five hundreds, the sixth embodiment being in the six
hundreds, the seventh embodiment being in the seven hundreds, the
eighth embodiment being in the eight hundreds, the ninth embodiment
being in the nine hundreds and the tenth embodiment being in the
ten hundreds. As shown in the drawings, only a portion of two
joined panels 142a, 142b; 242a, 242b; 342a, 342b; 442a, 442b; 542a,
542b; 642a, 642b; 742a, 742b; 842a, 842b; 942a, 942b; 1042a, 1042b
are shown. It is to be understood that a plurality of panels may be
used to form each sidewall 124, 224, 324, 424, 524, 624, 724, 824,
924, 1024. In addition, the novel joint 144, 244, 344, 444, 544,
644, 744, 844, 944, 1044 is only shown between one end of the two
panels 142a, 142b; 242a, 242b; 342a, 342b; 442a, 442b; 542a, 542b;
642a, 642b; 742a, 742b; 842a, 842b; 942a, 942b; 1042a, 1042b. It is
to be understood that a like joint is provided between each
adjacent end of each panel used to form the trailer sidewall.
Directing attention to the first embodiment of the novel joint
configuration 144 shown in FIG. 2, first and second composite
panels 142a, 142b are shown and are joined together by a logistics
plate 152 on the inside of the trailer 20 which extends along the
entire height of the panels 142a, 142b and by a splicing member 154
on the outside of the trailer 20 which extends along the entire
height of the panels 142a, 142b. The ends 156a, 156b of the panels
142a, 142b are spaced apart from each other when joined by the
logistics plate 152 and the splicing member 154 such that an air
pocket 158 is formed between the logistics plate 152 and the
splicing member 154.
Each end of the inner skins 148a, 148b of each panel 142a, 142b
have an end section 160a, 160b (only one of which is shown on each
panel 142a, 142b) which is coined or stepped down with an
intermediate section 161a, 161b of each panel 142a, 142b remaining
planar. The outer skin 150a, 150b of the panels 142a, 142b is not
coined and remains planar. When the end section 160a, 160b of each
inner skin 148a, 148b is coined, the core member 146a, 146b is
squeezed or compressed between the inner and outer skins 148a,
150a; 148b, 150b and the core member 146a, 146b may slightly
extrude outwardly from the ends of the skins 148a, 150a; 148b, 150b
and into the air pocket 158 formed between the panels 142a,
142b.
The logistics plate 152 is a flat member having an inner surface
and an outer surface and which has a plurality of spaced openings
or slots 162 therethrough along an intermediate portion of the
logistics plate 152. The slots 162 provide a means for which
equipment can be engaged, for example by a clip or a hook, to the
sidewall 24 of the trailer 20. The logistics plate 152 is
preferably formed from a heavier and stronger material than the
material that is used for the skins 148a, 150a; 148b, 150b to
provide the sidewall with strength and rigidity. When the logistics
plate 152 is joined with the inner skins 148a, 148b of the panels
142a, 142b, the outer surface of the logistics plate 152 sits
against the inner surfaces of the inner end sections 160a, 160b
such that the inner surface of the logistics plate 152 is flush
with the -inner surfaces of the intermediate sections 161a, 161b of
the inner skins 148a, 148b to provide a co-planar surface along the
length of the sidewall 24 in the interior of the trailer 20.
Because the ends of the logistics plate 152 are flush with the
intermediate sections 161a, 161b of the inner skins 148a, 148b,
snagging of cargo on the edges of the logistics plate 152 is
substantially prevented. The logistics plate 152 bridges the gap
between the panels 142a, 142b such that the slots 162 align with
the air pocket 158 so that clips or hooks can be engaged with the
slots 162.
The splicing member 154, which is like a post, is attached to the
outer surface of the outer skins 150a, 150b and extends to clear
the top and bottom rails 38, 40 of the trailer 20. The splicing
member 154 has flat end portions 164 which lie against the outer
surfaces of the outer skins 150a, 150b and an intermediate portion
166 which bulges outwardly from the end portions 164. When the
splicing member 154 is joined with the outer surfaces of the outer
skins 150a, 150b of the panels 142a, 142b, the inner surfaces of
the end portions 164 lie against the planar outer skins 150a, 150b
and the intermediate portion 166 bulges outwardly from the
sidewall. The splicing member 154 bridges the gap formed between
the panels 142a, 142b such that the bulging intermediate portion
166 aligns with the air pocket 158. Because the bulge is provided
on the outside of the trailer 20, a smooth inner surface is
provided within the trailer 20. This allows for more width within
the inside of the trailer 20 to load freight therein.
The logistics plate 152 and splicing member 154 are attached to the
first and second panels 142a, 142b by suitable means, such as
rivets 168, which extend through the logistics plate 152, the
respective coined sections 160a, 160b of the panels 142a, 142b and
the end portions 164 of the splicing member 154. The splicing
member 154 seals the junction between the panels 142a, 142b on the
exterior of the trailer 20 so as to seal the interior from
moisture.
Attention is now directed to the second embodiment of the novel
joint configuration 244 shown in FIG. 3. In this embodiment, first
and second composite panels 242a, 242b are joined together by a
logistics plate 252 on the inside of the trailer 20 which extends
along the entire height of the panels 242a, 242b and by a splicing
member 254 on the outside of the trailer 20 which extends along the
entire height of the panels 242a, 242b. The ends 256a, 256b of the
panels 242a, 242b are spaced apart from each other to provide a gap
therebetween when joined by the logistics plate 252 and the
splicing member 254 such that an air pocket 258 is formed between
the logistics plate 252 and the splicing member 254.
Each end of the outer skins 250a, 250b of each panel 242a, 242b
have an end section 263a, 263b (only one of which is shown on each
panel 242a, 242b) which is coined or stepped down with an
intermediate section 265a, 265b of each panel 242a, 242b remaining
planar. The inner skin 248a, 248b of the panels 242a, 242b is not
coined and remains planar. When the end section 263a, 263b of each
outer skin 250a, 250b is coined, the core member 246a, 246b is
squeezed or compressed between the skins 248a, 250a; 248b, 250b and
the core member 246a, 246b may slightly extrude outwardly from the
ends 256a, 256b of the panels 242a, 242b and into the air pocket
258.
The logistics plate 252 acts like a post and has end portions 270
which are flat and an intermediate portion 272 which bulges
inwardly from the end portions 270. The bulging intermediate
portion 272 has a plurality of spaced openings or slots 274
therethrough. The slots 274 provide a means for which equipment can
be engaged, for example by a clip or a hook, to the trailer
sidewall. The logistics plate 252 is preferably formed from a
heavier and stronger material than the material that is used for
the skins 248a, 250a, 248b, 250b to provide the sidewall 24 with
strength and rigidity. When the logistics plate 252 is joined with
the inner skins 248a, 248b of the panels 242a, 242b, the outer
surface of the end portions 270 sits against the inner surface of
the inner skins 248a, 248b such that the intermediate portion 272
bulges to the inside of the trailer 20. The logistics plate 252
bridges the gap formed between the panels 242a, 242b such that the
bulging intermediate portion 272 which has the slots 274
therethrough aligns with the gap.
The splicing member 254 is flat and extends to clear the top and
bottom rails 38, 40 of the trailer 20. When, the splicing member is
joined with the outer skins 250a, 250b of the panels 242a, 242b,
the inner surface of the splicing member 254 sits against the
coined end sections 263a, 263b such that the outer surface of the
splicing member 254 is flush with the outer surface of the
respective intermediate sections 265a, 265b of the outer skins
250a, 250b to provide a co-planar surface along the length of the
sidewall 24 on the outside of the trailer 20. The splicing member
254 bridges the gap formed between the panels 242a, 242b.
The logistics plate 252 and the splicing member 254 are attached to
the respective first and second panels 242a, ,242b big suitable
means, such as rivets 268, through the end portions 270 of the
logistics plate 252, the respective coined sections 263a, 263b of
the panels 242a, 242b and the splicing member 254. The splicing
member 254 seals the junction between the panels 242a, 242b on the
exterior of the trailer 20 so as to seal the interior from
moisture.
Directing attention to the third embodiment of the novel joint
configuration 344 shown in FIG. 4, first and second composite
panels 342a, 342b are joined together by a logistics plate 352 on
the inside of the trailer 20 which extends along the entire height
of the panels 342a, 342b and by a splicing member 354 on the
outside of the trailer 20 which extends along the entire height of
the panels 342a, 342b. The ends 356a, 356b of the panels 342a, 342b
are spaced apart from each other to provide a gap therebetween when
joined by the logistics plate 352 and the splicing member 354 such
that an air pocket 358 is formed between the logistics plate 352
and the splicing member 354.
Each end of the inner skins 348a, 348b of each panel 342a, 342b has
an end section 360a, 360b (only one of which is shown on each panel
342a, 342b) which is coined or stepped down with an intermediate
section 361a, 361b of each panel 342a, 342b remaining planar. Each
end of the outer skins 350a, 350b of each panel 342a, 342b have an
end section 363a, 363b (only one of which is shown on each panel
342a, 342b) which is coined or stepped down with an intermediate
section 365a, 365b of each panel 342a, 342b remaining planar. When
the end sections 360a, 363a; 360b, 1363b are coined, the respective
core members 346a, 346b are squeezed or compressed between the
skins 348a, 348b; 350a, 350b and may slightly extrude outwardly
from the ends 356a, 356b of the panels 342a, 342b and into the air
pocket 358.
The logistics plate 352 and the splicing member 354 are identical
in construction to the second embodiment of the logistics plate 252
and the splicing member 254 shown and described with respect to
FIG. 3. Therefore, the specifics of the construction of the
logistics plate 352 and the splicing member 354 are not repeated
herein and instead, the reference numerals are denoted with like
numerals and are shown in the drawings.
When the logistics plate 354 is joined with the inner skins 348a,
348b of the panels 342a, 342b, the outer surfaces of the flat end
portions 370 sit against the inner surfaces of the respective
coined end sections 360a, 360b such that the inner surfaces of the
end portions 370 are flush with the inner surfaces of the
intermediate sections 361a, 361b of the inner skins 348a, 348b and
the intermediate portion 372 of the logistics plate 352 bulges to
the inside of the trailer 20. The ends 356a, 356b of the panels
342a, 342b are spaced apart from each other. Because the inner
surfaces of the end portions 370 are flush with the inner surfaces
of the intermediate sections 361a, 361b of the skins 348a, 348b,
snagging of cargo on the edges of the logistics plate 352 is
substantially prevented. The logistics plate 352 bridges the gap
formed between the panels 342a, 342b such that the bulging
intermediate portion 372, which has the openings or slots 372
therein, aligns with the air pocket 358.
When the flat splicing member 354 is joined with the outer skins
350a, 350b of the panels 342a, 342b, the inner surface of the
splicing member 354 sits against the outer surfaces of the coined
end sections 363a, 363b such that the outer surface of the flat
splicing member 354 is flush with the outer surfaces of the
intermediate sections 365a, 365b of the outer skins 350a, 350b to
provide a co-planar surface along the length of the sidewall 24 on
the outside of the trailer 20. The splicing member 354 bridges the
gap formed between the panels 342a, 342b.
The logistics plate 352 and the splicing member 354 are attached to
the respective first and second panels 342a, 342b by suitable
means, such as rivets 368, through the end portions 370 of the
logistics plate 352, the coined portions of the panels 342a, 342b
and the splicing member 354. The splicing member 354 seals the
junction between the panels 342a, 342b on the exterior of the
trailer 20 so as to seal the interior from moisture.
Attention is now directed to the fourth embodiment of the novel
joint configuration 444 shown in FIGS. 5 and 6. In this embodiment,
first and second composite panels 442a, 442b are joined together by
a logistics plate 452 on the inside of the trailer 20 which extends
along the entire height of the panels 442a, 442b and the splicing
member provided in the previous embodiments has been
eliminated.
At one end of the first panel 442a, as shown in FIGS. 5 and 6, the
outer skin 450a has a length that is substantially longer than the
length of the inner skin 448a. The ends of the inner and outer
skins 448a, 450a freely project beyond the end of the core member
446a so as to leave an open area between the inner and outer skins
448a, 450a at the ends of the first panel 442a. At the other end of
the panel 442a (not shown), the inner and outer skins 448a, 450a
freely project beyond the end of the core member 446a the same
distance so as to leave an open area between the inner and outer
skins 448a, 450a.
At one end of the second panel 442b, the inner and outer skins
448b, 450b are of the same length and freely project beyond the end
of the core member 446b the same amount so as to leave an open area
between the inner and outer skins 448b, 450b. This structure is
identical to the end of panel 442a which is not shown. At the
opposite end of the second panel 442b, the construction is
identical to the end of the first panel 442a shown in FIGS. 5 and
6.
The logistics plate 452 is formed by extruded or formed aluminum.
The logistics plate 452 has flat end portions 470 with an
intermediate portion 472 that bulges inwardly therefrom. The end
portions 470 are approximately the same thickness as the thickness
of the core members 446a, 446b and each have a length which is
approximately equal to the distance between the end of each inner
skin 448a, 448b to the respective core members 446a, 446b. The
bulging intermediate portion 472 has a thickness which is
substantially less than the thickness of the end portions 470 and
has a plurality of spaced openings or slots 474 along the length
thereof.
To assemble the logistics plate 452 with the first and second
panels 442a, 442b, the end portions 470 of the logistics plate 452
are inserted between the inner and outer skins 448a, 450a; 448b,
450b of the first and second panels 442a, 442b such that the ends
of the end portions 470 generally abut against the ends of the core
members 446a, 446b. The ends of the inner skins 448a, 448b sit
adjacent to the junction between the respective end portions 470
and the bulging intermediate portion 472 of the logistics plate
452. The outer skin 450a of the first panel 442a extends behind the
logistics plate 452 and lies against the outer skin 450b of the
second panel 442b. The outer skin 450a may lie against outer skin
450b on the inside thereof or the outside thereof. An air pocket
458 is formed between the bulging intermediate portion 472 of the
logistics plate 452 and the outer skin 450a of the first panel
442a. The slots 474 align with the air pocket 458 so that clips,
hooks or the like can be attached thereto for attaching equipment
to the logistics plate 452. Rivets 468 are engaged through the
respective inner skins 448a, 448b, the respective end portions 470
of the logistics plate 452, the respective outer skins 450a, 450b
and the extension of the outer skin 450a.
The extension of the first panel outer skin 450a eliminates the
need for the separate splicing member as used in the first, second
and third embodiments. The outer skin 450a is very thin, however,
and, as such, does not provide as much reinforcement as the
splicing member provides. The extension of the first panel outer
skin 450a seals the junction between the panels 442a, 442b on the
exterior of the trailer 20 so as to seal the interior from
moisture.
Directing attention to the fifth embodiment of the novel joint
configuration 544 shown in FIG. 7, this embodiment is the same as
the joint configuration 444 shown in the fourth embodiment except
that the flat end portions 570 of the logistics plate 552 are not
the same thickness as the core members 546a, 546b. Instead, the
flat end portions 570 and the bulging intermediate portion 572 of
the logistics plate 552 are of a substantially uniform
thickness.
To fill the space between the respective end portions 570 of the
logistics plate 552 and the respective outer skins 550a, 550b, an
insert 576 is provided in each such space. Each insert 576 is made
of high density plastic or metal and completely fills the space
between the outer skin 550a, 550b and the end portion 570 of the
logistics plate 552. The rivets 568 are engaged through the
respective inner skins 548a, go 548b, the respective end portions
570 of the logistics plate 552, the respective inserts 576 and the
respective outer skins 550a, 550b. When the rivets 568 are inserted
through the panels 542a, 542b, the insert 576 substantially
prevents compression of the panels 542a, 542b, which can occur
during the insertion of a rivet because the core member 546a, 546b
is made of a compressible material.
Alternatively, the logistics plate 552 could be attached to the
inner surface of the inner skins 548a, 548b with the respective
inserts 576 completely filling the space between the skins 548a,
550a; 548b, 550b. In addition, the logistics plate 552 could be
attached to the inner surface of the inner skins 548a, 548b, the
insert 576 eliminated, and the core member 546a, 546b used to
completely fill the space between the skins 548a, 550a; 548a,
550a.
Directing attention to the sixth embodiment of the novel joint
configuration 644 shown in FIGS. 8 and 9, first and second
composite panels 642a, 642b are joined together by a logistics
plate 652 on the inside of the trailer 20 which extends along the
entire height of the panels 642a, 642b and, like the fourth and
fifth embodiments, the splicing member provided in the previous
embodiments has been eliminated.
At each end of the first panel 642a, the outer skin 650a has a
length that is substantially longer than the length of the inner
skin 648a. The ends of the inner and outer skins 648a, 650a freely
project beyond the end of the core member 646a so as to leave an
open area between the inner and outer skins 648a, 650a at each end
of the first panel 642a.
The second panel 642b is similarly constructed to the first panel
642a. At each end of the second panel 642b, the outer skin 650b has
a length that is substantially longer than the length of the inner
skin 648b. The ends of the inner and outer skins 648b, 650b freely
project beyond the end of the core member 646b so as to leave an
open area between the inner and outer skins 648b, 650b at each end
of the second panel 642b.
The logistics plate 652 is identical in construction to that
described with respect to the fourth embodiment. Thus, a repetition
of the construction of the logistics plate 652 is not repeated
herein.
To assemble the logistics plate 652 with the first and second
panels 642a, 642b, the flat end portions 670 of the logistics plate
652 are inserted between the inner and outer skins 648a, 650a;
648b, 650b of the first and second panels 642a, 642b such that the
ends of the end portions 670 generally abut against the ends of the
core members 646a, 646b. The ends of the inner skins 648a, 648b sit
adjacent to the junction between the respective end portions 670
and the bulging intermediate portion 672 of the logistics plate
652. The outer skin 650b of the second panel 642b extends behind
the logistics plate 652 and lays against the outer skin 650a of the
first panel 642a. The outer skin 650a of the first panel 642a
extends behind the logistics plate 652 and lies against the outer
skin 650b of the second panel 642b. The outer skin 650a may lie
against outer skin 650b on the inside or the outside of outer skin
650b. An air pocket 658 is formed between the bulging intermediate
portion 672 of the logistics plate 652 and the outer skin 650a of
the first panel 642a. The openings or slots 674 align with the air
pocket 658 so that clips or the like can be attached thereto for
attaching equipment to the logistics plate 652. Rivets 668 are
engaged through the respective inner skins 648a, 648b, the
respective end portions 670 of the logistics plate 652 and the
respective outer skins 650a, 650b and the extensions of the outer
skins 650a, 650b.
Because the outer skin 650a of the first panel 642a, overlays the
outer skin 650b of the second panel 642b, a bend 678 is provided in
the outer skin 650a of the first panel 642a so that the outer skins
650a, 650b lie against each other. This forms a double thickness
behind the intermediate portion 672 of the logistics plate 652 to
provide more strength and rigidity than when a single thickness is
used, such as that shown in the fourth and fifth embodiments. The
extension of the outer skins 650a, 650b of the first and second
panels 642a, 642b eliminates the need for the separate splicing
member as shown in the previous embodiments. If desired, inserts,
like those provided in the fifth embodiment, may be provided. The
extensions of the outer skins 650a, 650b seal the junction between
the panels 642a, 642b on the exterior of the trailer 20 so as to
seal the interior from moisture.
In the fourth, fifth and sixth embodiments of the novel composite
joint configurations 444, 544, 644, the rivets 468, 568, 668 are
engaged by using the method and apparatus disclosed in co-pending
U.S. patent application Ser. No. 08/620,999, entitled "Method of
Punching A Composite Plate", now U.S. Pat. No. 5,774,972, which is
commonly owned by the assignee herein and which disclosure is
herein incorporated by reference. If desired, holes can be provided
through the logistic panel 452, 552, 652 and the panels 442a, 442b;
542a, 542b; 642a, 642b.
Attention is now directed to the seventh embodiment of the novel
joint configuration 744, shown in FIG. 11, which has first and
second composite panels 742a, 742b. One of the panels 742b is shown
in FIG. 10. It is to be understood that the other panels used to
construct the trailer sidewall are identical in construction. At
one end of the panel 742b, as shown in FIG. 10, the inner and outer
skins 748b, 750b are longer than its associated core member 746b so
as to freely project beyond the end of the core member 746b. At the
opposite end of the panel 742b, the inner and outer skins 748b,
750b are stepped down or coined so as to provide an end portion
780b which has a thickness that is less than the thickness of the
remainder of the panel 742b. The edge of the core member 746b is
generally flush with the end of the coined end portion 780b of the
panel 742b, however, when the skins 748b, 750b are coined, some
core material may extrude outwardly therefrom.
As shown in FIG. 11, to connect the panels 742a, 742b together to
form a sidewall 24 of the trailer 20, the coined end portion 780b
of one panel 742b is inserted between the freely projecting inner
and outer skins 748a, 750a of the adjacent panel 742a. When
interconnected together, the outer surface of the inner skin 748b
of panel 742b lies against the inner surface of the inner skin 748a
of panel 742a and the outer surface of the outer skin 750b of panel
742b lies against the inner surface of the outer skin 750a of panel
742a. When the panels 742a, 742b are joined together, because of
the coined end portion 780b, the inner surfaces and outer surfaces
of the panels 742a, 742b are smooth and flush along the length
thereof on the inside and outside of the trailer 20. An insert,
like that disclosed in the fifth embodiment, may replace the core
material between the skins in the coined end portion 780b, if
desired. Rivets 768 are engaged through the freely projecting ends
of the inner and outer skins 748a, 750a and the coined end portion
780b.
Attention is now directed to the eighth embodiment of the novel
joint configuration 844, shown in FIG. 13, which has first and
second composite panels 842a, 842b. One of the panels 842a is shown
in FIG. 12. It is to be understood that the other panels used to
construct the trailer sidewall 24 are identical in construction. At
each end of the panel 842b, as shown in FIG. 12, the inner and
outer skins 848b, 850b are longer than its associated core member
846b so as to freely project beyond the ends of the core member
846b. The panel 842b tapers from one end to the other end such that
the distance D1 between the inner and outer skins 848b, 850b at one
end is greater than the distance D2 between the inner and outer
skins 848b, 850b at the other end. Thus, the core member 846b
tapers from one end of the panel 842b to the other end of the panel
842b.
As shown in this embodiment, an insert 876, like the insert 576 in
the fifth embodiment, is provided between the freely projecting
skins 848b, 850b at the end of the panel 842b which has the lesser
thickness. The insert 876 completely fills the space between the
inner and outer skins 848b, 850b and is made of high density
plastic, metal or the like. When the rivets 868 are inserted
through the panels 842a, 842b, the insert 876 substantially
prevents compression of the panels 842a, 842b, which can occur
during the insertion of a rivet because the core member 846a, 846b
is made of a compressible material. Alternatively, the insert 876
could be eliminated and the core member 846b extended to fill the
space.
To connect the panels together to form a sidewall 24 the trailer
20, the smaller end of one panel 842b is inserted into the larger
end of the adjacent panel 842a. When interconnected together, the
outer surface of the inner skin 848b of panel 842b lies against the
inner surface of the inner skin 848a of panel 842a and the outer
surface of outer skin 850b of panel 842b lies against the inner
surface of the outer skin 850a of panel 842a.
In the seventh and eighth embodiments of the novel joint
configuration 744, 844, each rivet 768, 868 is engaged with the
panels by using the method and apparatus disclosed in co-pending
U.S. patent application Ser. No. 08/620,999 which disclosure has
been herein incorporated by reference. During this punching
process, the core material may extrude and fill any gaps between
the end of the panel and the core member of the other panel. If
desired, holes can be provided through the skins of the one panel
and the reduced portion of the other panel through which the rivets
are engaged.
Directing attention to the ninth embodiment of the novel joint
configuration 944 shown in FIG. 15, this embodiment is the same as
the joint configuration 144 shown in the first embodiment except
that the construction of the splicing member 954 is different. It
is to be understood that the splicing member 954 described with
respect to this embodiment can be used on any of the embodiments in
which a splicing member is provided, e.g., FIG. 5.
The splicing member 954, which is like a post, is attached to the
outer surface of the outer skins 950a, 950b and is mounted under
and extends between the top and bottom rails 38a, 40a of the
trailer 20a. The splicing member has a flat top portion 970, a flat
bottom portion 972 and flat side portions 974 which lie against the
outer surfaces of the outer'skins 950a, 950b, and an intermediate
portion 966 which bulges outwardly from the top, bottom and side
portions 970, 972, 974. When the splicing member 954 is joined with
the outer surfaces of the outer skins 950a, 950b of the panels
942a, 942b, the inner surfaces of the side portions 974 lie against
the planar outer skins 950a, 950b and the intermediate portion 966
bulges outwardly from the sidewall. The bulging intermediate
portion 966 of the splicing member 954 bridges the air pocket 958
formed between the panels 942a, 942b and aligns with the air pocket
958. The bulging intermediate portion 966 provides for more space
within the air pocket 958 to allow for the attachment of members,
such as clip or hooks, to the slots 962 of the logistics plate
member 952. Because the bulge is provided on the outside of the
trailer 20a, a smooth inner surface is provided within the trailer
20a. This allows for more width within the inside of the trailer
20a to load freight therein.
The flat top portion 970 and the flat bottom portion 972 of the
splicing member 954 facilitate connection of the panels 942a, 942b
to the top and bottom rails 38a, 40a of the trailer 20a. In order
to connect the sidewalls 24a to the roof 30a, the roof 30a is laid
on top of the edges of the sidewalls 24a. Each top rail 38a is
connected by seating the first portion 39a against the roof 30a and
the second portion 41a against the respective sidewalls 24a. The
second portion 41a of each top rail 38a sits over the flat top
portion 970 of each splicing member 954 provided along the length
of the respective sidewalls 24a. Each bottom rail 40a connects the
floor 32a and the respective sidewalls 24a in the same manner as
each top rail 38a connects the roof 30a and the respective
sidewalls 24a. The flat top portions 970 and the flat bottom
portions 972 facilitate in the connection of the panels 942a, 942b
to the top and bottom rails 38a, 40a of the trailer 20a because
they allow the rails 38a, 40a, which have flat second portions 41a,
to easily be positioned against the splicing member 954. If the
splicing members 954 did not have the flat top and bottom portions
970, 972, but rather have the bulging intermediate portion 966
extending the entire height of each splicing member 954, the rails
38a, 40a would have to be formed to include bulges to fit over the
bulging intermediate portion 966 of each splicing member 954. Thus,
the use of the flat top and bottom portions 970, 972 on the
splicing member 954 allows for a much easier connection between the
splicing member 954 than if the flat top and bottom portions 970,
972 were not a part of the splicing member 954.
The logistics plate 952 and the splicing member 954 are attached to
the first and second panels 942a, 942b by suitable means, such as
rivets 968, which extend through the logistic, plate 952, the
respective coined sections 960a, 960b of the panels 942a, 942b, the
respective core members 946a, 946b, the respective outer skins
950a, 950b, and the respective side portions 974 of the splicing
member 954. The splicing member 954 seals the junction between the
panels 942a, 942b on the exterior of the trailer 20a so as to seal
the interior from moisture. Moreover, because the flat top and
bottom portions 970, 972 are seated under the top and bottom rails
38a, 40a, moisture does not penetrate into the interior of the
trailer 20a and cause damage to the freight of the trailer 20a or
to the trailer 20a itself.
In the first, second, third and ninth embodiments of the novel
composite joint constructions 144, 244, 344, 944, to engage the
rivets 168,.268, 368, 968 with the logistics plate 152, 252, 352,
952 the splicing member 154, 254, 354, 954 and the respective first
and second panels 142a, 142b; 242a, 242b; 342a, 342b; 942a, 942b
each rivet 168, 268, 368, 968 is engaged by using the method and
apparatus disclosed in co-pending U.S. patent application Ser. No.
08/620,999, which disclosure has been incorporated by reference.
Coining the ends of the panels 142a, 142b; 242a, 242b; 342a, 342b;
942a, 942b as described herein, condenses the plastic core member
146a, 146b; 246a, 246b; 346a, 346b; 946a, 946b sufficiently to
support clamping force or pressure from the rivets 168, 268, 368,
968 without subsequent loosening. If desired, holes can be provided
through the logistic panel 152, 252, 352, 952<and the splicing
member 154, 254, 354, 954 through which the rivets 168, :268, 368,
968 are engaged.
In addition, in the first, second, third and ninth embodiments of
the composite joint configurations 144, 244, 344, 944, it is
envisioned that an insert, as discussed herein with respect to the
fifth embodiment shown in FIG. 7, can be provided in the
construction of these embodiments of the trailer sidewalls.
Attention is now directed to the tenth embodiment of the novel
joint configuration 1044 shown in FIG. 16. In this embodiment,
first and second composite panels 1042a, 1042b are joined together
by a logistics plate 1052 on the inside of the trailer 20 which
extends along the entire height of the panels 1042a, 1042b and the
splicing member provided in the first, second, third and ninth
embodiments has been eliminated.
At one end of the first panel 1042a, as shown in FIG. 16, the outer
skin 1050a has a length that is substantially longer than the
length of the inner skin 1048a. The end of the outer skin 1050a
freely projects beyond the e:d of the core member 1046a and the
inner skin 1048a. At the other end of the panel 1042a (not shown),
the inner skin 1048a, the outer skin 1050a and the core member
1046a all extend the same length in an identical structure to the
end of the second panel 1042b shown in FIG. 16.
At one end of the second panel 1042b, as shown in FIG. 16, the
inner skin 1048b, the outer skin 1050b and the core member 1046b
all extend the same length. At the opposite end of the second panel
1042b (not shown), the construction is identical to the end of the
first panel 1042a shown in FIG. 16.
Each of the inner skins 1048a, 1048b of each panel 1042a, 1042b has
an inner surface 1073a, 1073b. Each end of the inner skins 1048a,
1048b of each panel 1042a, 1042b has an end section 1074a, 1074b
(only one of which is shown on each panel 1042a, 1042b) which
includes a groove 1076a, 1076b formed therein proximate to, but
spaced from, the end of the panels 1042a, 1042b. The remainder of
the inner surfaces 1073a, 1073b of the inner skins 1048a, 1048b of
the panels 1042a, 1042b remain planar. When the groove 1076a, 1076b
is formed in the end section 1074a, 1074b of each inner skin 1048a,
1048b, the core member 1046a, 1046b is squeezed or compressed
between the inner and outer skins 1048a, 1050a; 1048b, 1050b and
the core member 1046a, 1046b may slightly extrude outwardly from
the ends of the skins 1048a, 1050a; 1048b, 1050b and into the air
pocket 1058 formed between the panels 1042a, 1042b. The grooves
1076a, 1076b may be formed by coining.
The logistics plate 1052 acts like a post and is a member having a
flat intermediate portion 1078 with opposite edges 1080a, 1080b
which are rolled. The logistics plate 1052 has an inner surface
1081 that is planar, except for the opposite edges 1080a, 1080b. A
plurality of spaced openings or slots 1062 are provided through the
flat intermediate portion 1078 of the logistics plate 1052. The
slots 1062 provide a means for which equipment can be engaged, for
example by a clip or a hook, to the sidewalls 24 of the trailer 20.
The logistics plate 1052 is preferably formed from a heavier and
stronger material than the material that is used for the skins
1048a, 1050a; 1048b, 1050b to provide the sidewall with strength
and rigidity.
When the logistic plate 1052 is joined with the inner skins 1048a,
1048b of the panels 1042a, 1042b, the rolled edges 1080a, 1080b of
the logistics plate 1052 sit within the respective grooves 1076a,
1076b in the end sections 1074a, 1074b, such that the opposite
edges 1080a, 1080b are within substantially the same plane as the
inner surfaces 1073a, 1073b of the inner skins 1048a, 1048b of each
panel 1042a, 1042b, which is a different plane than the inner
surface 1081 of the logistics plate 1052, and the flat intermediate
portion 1078 spans the air pocket 1058 such that the slots 1062
align with the air pocket 1058 so that clips or hooks can be
engaged with the slots 1062. The rolled edges 1080a, 1080b, when
seated in the grooves 1076a, 1076b, provide a smooth transition
from the logistics plate 1052 to the inner skins 1048a, 1048b to
substantially prevent snagging of cargo on the edges of the
logistics plate 1052. Rivets 1068 are engaged through the ends of
the logistics plate 1052, the respective inner skins 1048a, 1048b,
the respective core members 1046a, 1046b and the respective outer
skins 1050a, 1050b.
The extension of the first panel outer skin 1050a eliminates the
need for the separate splicing member as used in the first, second,
third and ninth embodiments described herein. The outer skin 1050a
is very thin, however, and, as such, does not provide as much
reinforcement as the splicing member provides. The extension of the
first panel outer skin 1050a seals the junction between the panels
1042a, 1042b on the exterior of the trailer 20 so as to seal the
interior of the trailer 20 from moisture.
While preferred embodiments of the present invention are shown and
described, it is envisioned that those skilled in the art may
devise various modifications of the present invention without
departing from the spirit and scope of the appended claims. For
example, in any of the embodiments which uses a logistics plate,
the logistics plate may be flat or bulge inwardly. Also, in any of
the embodiments which uses a splicing member, the splicing member
may be flat or bulge outwardly and may have the flat top and bottom
portions if a bulge is provided. An insert could be provided in any
of the embodiments or eliminated in the embodiments where it is
shown.
